PIC18LF26J13-I/SO 概要
A PIC18 microcontroller is a member of Microchip's 8-bit PIC (Peripheral Interface Controller) family built on a Harvard RISC architecture with a modified instruction set optimized for deterministic single-cycle execution (except branches). PIC18F/LF parts sit between the baseline PIC10/12/16 line and the 16-bit dsPIC/PIC24 family, offering a richer peripheral set (12-bit ADC, CCP/SCCP, MSSP, EUSART) and larger memory while remaining programmable in nanolit. Within the PIC18 hierarchy, the LF sub-line is the low-Vdd branch designed for battery-powered XLP (eXtreme Low Power) applications, with sleep currents measured in nanoamps.
Key features of the PIC18LF26J13 include 64KB Flash self-programmable via ICSP, 4KB SRAM, up to 28 I/O, 12-bit A/D converter with up to 10 channels, multiple Enhanced CCP (ECCP) and Capture/Compare/PWM (CCP) modules, two MSSP (SPI/I2C) ports, two EUSART modules with LIN support, real-time clock (RTCC) with calendar, and nanoWatt XLP technology offering <100 nA typical sleep current with RTCC and WDT active. The integrated 48MHz precision internal oscillator removes the external crystal in many cost-sensitive designs.
The PIC18LF26J13 uses an enhanced Harvard core with 16-bit instructions and a hardware multiplier, executing most instructions in one cycle (~83 ns at 48 MHz FOSC). On-chip peripherals are mapped via a Peripheral Pin Select (PPS) module, allowing flexible pin remapping of digital functions. The 12-bit ADC supports up to 16 channels with automated channel scanning, while the CTMU module provides touch sensing and capacitive proximity measurement.
Typical applications include battery-powered sensor nodes, USB peripherals, home appliances with LCD/keypad interfaces, industrial control panels, and low-power wireless sensor networks paired with sub-GHz transceivers. The combination of nanoWatt sleep modes and 12-bit ADC makes the part suitable for energy-harvesting and remote-monitoring designs.
When designing with this device, ensure VDD decoupling is placed close to the pins and that the internal 48 MHz configured for precision (INTOSC) accuracy is acceptable for timing-critical peripherals such as EUSART. Pin-compatible PIC18F26J13 variants operate over a wider 2.0V-3.6V/4.2V-5.5V range but consume more active current.

主な用途
PIC18LF26J13-I/SO の用途: 6 件s: Battery-Powered Sensor Nodes, Home Appliance Control Panels, Industrial Control and Monitoring, USB-to-UART Bridge Devices, Low-Power Wireless Sensor Networks, LCD Display Driver Boards.
Battery-Powered Sensor Nodes
The PIC18LF26J13-I/SO's nanoWatt XLP technology delivers typical sleep currents below 100 nA with the 32 kHz crystal and WDT active, extending coin-cell life in remote sensor deployments. Its 12-bit ADC with up to 10 channels supports ratiometric temperature, humidity, and voltage sensing at better than 0.025% resolution, while the 48 MHz core allows duty-cycled wake-ups to compress and transmit data in milliseconds. The 2.0V-3.6V LF Vdd range lets the part run directly from a single CR2032 or two AA alkaline cells without boost regulation, simplifying BOM cost and quiescent current.
おすすめ
Home Appliance Control Panels
The PIC18LF26J13-I/SO integrates the peripherals needed for appliance HMI: CCP/PWM for motor or buzzer drive, 12-bit ADC for analog front-panel sense inputs, EUSART modules for communication with inverter boards, and MSSP for EEPROM or LCD module I/O. The 28-pin SOIC provides enough I/O for 4x4 keypads, 7-segment displays, and rotary encoder inputs while the XLP modes save power during standby. Programming in nanolit or MPALB with Microchip's free MPLAB X IDE reduces development time versus legacy PIC16 designs.
おすすめ
Industrial Control and Monitoring
The PIC18LF26J13-I/SO's 12-bit ADC, RTCC calendar, and EUSART with LIN-bus support suit it for industrial control panel applications including PLC I/O expanders, sensor transmitters, and motor-control daughter boards. Hardware PWM via the ECCP module drives MOSFET gates directly, while the MSSP port streams data to a host PLC over SPI. The -40C to +85C industrial temperature range meets IEC 60068-2 environmental stress profiles, and on-chip CRC helps verify configuration EEPROM integrity against brown-out events common in factory floors.
おすすめ
USB-to-UART Bridge Devices
Although the PIC18LF26J13 lacks integrated USB, it can serve as the UART-side controller in a USB bridge module when paired with a dedicated USB transceiver IC such as MCP2200 or MCP2221. The two EUSART modules support up to 921.6 kbps and LIN 1.3 protocol, while the MSSP provides SPI bridging to sensors or flash memories. The 64KB Flash holds USB-CDC stack shims, command parsers, and DFU bootloaders for firmware updates over the bridge. This pairing is common in low-volume instrumentation and OEM cable assemblies.
おすすめ
Low-Power Wireless Sensor Networks
Paired with sub-GHz or 2.4 GHz transceivers such as the MRF24J40 or RN2483, the PIC18LF26J13-I/SO forms the MCU half of an energy-harvesting wireless sensor node. The 48 MHz core handles 6LoWPAN or LoRaWAN MAC-layer encryption within microsecond wake windows, while the nanoWatt sleep current preserves harvested energy budgets. The 12-bit ADC digitizes piezoelectric or photovoltaic harvest voltages, and the RTCC timestamps each transmission to within seconds over months of unattended operation. The compact SOIC-28 footprint fits even small sensor packages.
おすすめ
LCD Display Driver Boards
The PIC18LF26J13-I/SO drives character LCDs and small graphic LCDs via its MSSP (SPI) port, while the CCP/PWM channels generate contrast-bias voltages and backlight dimming. Peripheral Pin Select (PPS) remaps digital functions to any available I/O pin, simplifying PCB layout for compact display modules. The 64KB Flash holds multi-language bitmap font tables, and the 4KB RAM buffers full-screen updates at low refresh rates. With its SOIC-28 footprint and 2.0V-3.6V LF range, the part integrates directly into battery-powered remote controls and point-of-sale terminals.

設計ノート
Estimated: at VDD=3.3V, FOSC=48 MHz, the PIC18LF26J13-I/SO draws approximately 15 mA active. For battery designs, switch to the internal 31 kHz LFINTOSC and enter Sleep mode between sample intervals. The nanoWatt XLP Sleep mode with RTCC + WDT active draws under 100 nA typical per the Microchip datasheet. Use the VREGPM bit to disable the on-chip regulator on LF parts to save additional quiescent current when the system VDD is already in range.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) with a short, wide trace to the VSS pin (pin 19). For designs with multiple VDD/VSS pairs (pin 8/19 and pin 20), use a low-impedance ground pour and star-ground the analog AGND reference to the MCU VSS pin. Avoid routing high-speed signals (SPI clock, EUSART) near analog ADC traces to prevent digital switching noise from coupling into sensitive measurements.
Do not confuse the 'LF' (low-Vdd) prefix with 'Low Frequency' oscillator mode. The LF device operates from 2.0V-3.6V across all oscillator modes including 48 MHz HFINTOSC. Also note that the PIC18LF26J13 does not include on-chip USB; firmware libraries for USB require a PIC18F part with the USB peripheral (such as PIC18F14K50 or PIC18F25K50). Verify the configuration bits (CONFIG1L) for the oscillator mode and PLL to avoid unintentional 4x PLL activation on first programming.
For designs using the MSSP module in SPI mode at frequencies above 8 MHz, add 22-33 ohm series resistors on the SCK and SDO lines to dampen transmission-line ringing on long PCB traces. The PIC18LF26J13's drive strength is configurable via the PADCFG register; in noisy environments reducing the drive slew rate can lower EMI while maintaining signal integrity for sub-10 MHz peripherals.
